Recall that in Erik Erikson's (1968) model of human development, the stage of identity vs role confusion emerges in early adolescence. Although the teenage years are seen as the key period for identity development, this process in fact continues throughout adulthood.
The next major challenge, according to Erikson's (1968) model, is to establish intimacy with another person without losing one's sense of individuality. Intimacy can be defined as a satisfying relationship with another person - i.e. the meeting of two identities. A stable identity is required before intimacy can be achieved - possibly because an individual with a fragile identity risks losing oneself in union with another. Inability to achieve intimacy potentially leads to isolation. (Erikson, 1968)
The young adult capable of achieving intimacy is
These young adults trust in the sense that they can confess fears and vulnerability to an intimate partner. Intimate partners will be supportive and honest.
Identity and intimacy may be affected throughout the lifespan by major events such as death of a loved one, new job, new lifestyle or educational changes. Thus Erikson's (1968) theory can be applied each time an individual faces a major change. In each instance there may be issues of trust, autonomy, identity etc.
A 10-year longitudinal study of 93 young people in Germany found 48% of its participants having intimate, well-balanced, and enduring relationships by the age of 25 (Beyers & Seiffge-Krenke, 2010). The other 52% were placed in the following categories:

In other words - young people who develop a sense of who they are in their teenage years are more likely to engage in satisfying intimate relationships in their twenties.
Some possible components of intimacy are:
